Accordingly, it should be apparent to those skilled in the art that the following description of exemplary embodiments of the present disclosure are provided for illustration purpose only and not for the purpose of limiting the disclosure as defined by the appended claims and their equivalents.
The present invention may be implemented in an electronic device including a mobile terminal such as, for example, a smart phone and a mobile telecommunication terminal. Hereunder, a portable terminal is used as an example for the electronic device.
The present disclosure relates to a mobile terminal for mounting a motion measure sensor thereon and performing screen unlock based on motion information of the terminal measured by the mounted motion measure sensor, and a method thereof.
FIG. 1 illustrates a block diagram of a mobile terminal executing a screen unlock based on a motion according to an exemplary embodiment of the present disclosure.
Referring to FIG. 1, the mobile terminal 100 may include a motion measure unit 110, a motion pattern storage 120, a controller 130, a touch pattern storage 140, a touch pattern comparator 150, and an image execute unit 160. Here, the mobile terminal may include not only a Personal Digital Assistant (PDA), a cellular phone, a smart phone, a notebook, a tablet, etc. classified for each terminal type, and a mobile communication terminal such as a Personal Communication Service (PCS) phone, a Global System for Mobile communications (GSM) phone, a Wideband Code Division Multiple Access (W-CDMA) phone, a CDMA-2000 phone, a Mobile Broadband System (MBS) phone, etc. classified for each communication scheme, but also a mobile terminal such as an MP3 player, a Portable Multimedia Player (PMP), a Play Station Portable (PSP), etc. that can reproduce a moving picture or sound or install an application such as games and thus can produce moving pictures or sound or execute an application such as games. A touch detect display (not shown) may be included in the mobile terminal. The touch detect display may also be called as a touch sensitive display or a touch screen or a display.
The motion measure unit 110 may measure a motion direction of the mobile terminal 100, and a change of a velocity, an acceleration, an angular velocity, an angular acceleration, an amount of change in a slope, and an amount of change in a movement distance with respect to a relevant motion direction using a motion measure sensor such as a slope sensor, a gravity sensor, a velocity sensor, an acceleration sensor, an angular velocity sensor, a gyro sensor, etc. For example, when using the velocity sensor, an amount of change in a movement distance may be calculated using an actual measured time with respect to a measured velocity, and an acceleration may be calculated based on an amount of change in velocity per unit time. The motion measuring method using the motion measure sensor uses the known method, and detailed description thereof is omitted.
The motion pattern storage 120 stores a motion pattern set for the mobile terminal 100. For example, as illustrated in FIG. 2, the motion pattern storage 120 may set an x-axis direction of back and forth direction, an y-axis direction of left and right direction, and a straight direction of a z-axis of up and down direction with respect to the screen as basic directions, and set and store a motion pattern which in order of positive x-axis direction - negative x-axis direction - negative z-axis direction - positive y-axis direction are executed with respect to the set basic directions.
In addition, as illustrated in FIG. 3, the motion pattern storage 120 may set a left rotation direction and a right rotation direction around x-axis with respect to back and forth direction of the mobile terminal, a left rotation direction and a right rotation direction around y-axis with respect to left and right direction of the mobile terminal 100, and a left rotation direction and a right rotation direction around z-axis with respect to up and down direction of the mobile terminal 100 as basic directions, and set and store a motion pattern which in order ofright rotation around x-axis - left rotation around x-axis - left rotation around z-axis - right rotation around y-axis are executed with respect to the set basic directions.
In addition, the motion pattern storage 120 may combine a straight direction of FIG. 2 with a rotation direction of FIG. 3 to set a basic direction, and combine a motion of the straight direction with a motion of the rotation direction with respect to the set basic direction to set and store a motion pattern. Such a motion pattern may be set and stored when the mobile terminal 100 is manufactured, and may be realized such that the motion pattern may be set, changed, or deleted by a user.
The motion pattern of the electronic device may comprise a successive motion pattern of at least two times.
The controller 130 compares a motion of the mobile terminal 110 measured by the motion measure unit 110 with a motion pattern stored in the motion pattern storage 120. When the motion of the mobile terminal 110 coincides with the motion pattern stored in the motion pattern storage 120, the controller 130 may unlock the screen of the mobile terminal.
In executing screen unlock using the motion of the mobile terminal 100, the controller 130 may control the image execute unit 160 to display an image of opening a door on the screen. For example, when the screen lock is executed, the controller 130 may control the image execute unit 160 to display an image of a closed door on the screen, and may display a message saying "please, open the door", or output a voice message. In an example where a user moves the mobile terminal 100 such as rotating a handle of the door to push or pull the same, when the motion of the mobile terminal 100 coincides with a set motion pattern, the controller 130 may control to display an image of opening the door on the screen, and may output a message or a voice message saying "the door has been opened". At this point, the image displayed on the mobile terminal 100 may be changed variously depending on the motion pattern stored in the motion pattern storage 120. For example, when the motion pattern starts in a straight direction to the left or right, an image of a sliding door may be displayed. When the motion pattern starts in a straight direction to the upper or lower side, an image of a sliding door in the upper or lower side may be displayed. When a motion of the mobile terminal 100 measured by the motion measure unit 110 coincides with the motion pattern stored in the motion pattern storage 120 with respect to an image displayed on the screen of the mobile terminal 100, the controller 130 may control the image execute unit 160 to execute a screen of an operation of opening the door displayed on the mobile terminal 100, and simultaneously, control to unlock the screen.
The image execute unit 160 may display an image for screen unlock of the terminal 100 on the touchscreen. When a response signal is received via the touchscreen in response to the displayed image, the controller 130 may control the motion measure unit 110 to measure a motion of the mobile terminal 100. For example, the image execute unit 160 may display a door image 410, a key image 420, a handle image 430, and a key hole image 440 on the touchscreen as illustrated in FIG. 4. When a user drags the key image 420 to insert the key 420 into the key hole 440 via the touchscreen, the controller 130 may control the motion measure unit 110 to measure a motion of the mobile terminal 100. In this example, when the user inserts the key 420 into the key hole 440 via the touchscreen, the controller 130 may display an image where the key 420 is inserted into the key hole 440. After the key 420 is inserted, when a motion pattern of rotating the key counterclockwise and a motion pattern of rotating the handle 430 in a set direction are measured by the motion measure unit 110 as illustrated in FIG. 4, the controller 130 may execute the screen unlock. Alternatively, the image execute unit 160 may display a door image 510, a card key image 520, a handle image 530, and a card key insert hole image 540 as illustrated in FIG. 5. When a user inserts the card key 520 into the card key insert hole 540 via the touchscreen, the controller 130 may control the motion measure unit 110 to measure a motion of the terminal 100. In this example, when a front portion of the card key 520 coincides with the card key insert hole 540, the controller 130 may display an image where the card key 520 is inserted into the card key insert hole 540. When a motion pattern of rotating the handle 530 in a set direction is measured, the controller 130 may execute a screen unlock. Through this, it is possible to prevent an execution malfunction of measuring a motion of the terminal 100 and executing a screen unlock even when the user does not desire the screen unlock.
The images illustrated in FIGS. 4 and 5 and the descriptions thereof are provided for an exemplary purpose only for easy understanding of the present disclosure, and an operation for stating the displaying of an image for executing the screen unlock or the measuring of the motion of the motion measure unit 110 may be modified various ways.
As described above, the motion of the terminal may be measured using the motion measure sensor mounted on the mobile terminal, and the screen unlock may be unlocked based on a measured motion, so that a more intuitive and convenient user interface may be provided to the user.
Meanwhile, the screen unlock function based on the motion of the mobile terminal 100 may be used in combination of a touch pattern determination. For example, as illustrated in FIG. 6, the touch pattern storage 140 may store a touch pattern set by a user, and the touch pattern comparator 150 may compare the user's touch pattern input on the screen of the mobile terminal 100 with a touch pattern stored in the touch pattern storage 140. In this example, when the user's touch pattern input on the screen coincides with a touch pattern stored in the touch pattern storage 140, the controller 130 may control the image execute unit 160 to display images of a door and a key on the screen of the mobile terminal 100, and may output a message guiding to open the door using the displayed key in the form of voice or characters. In addition, when the user drags the key up to the door in response to the output guide message, the controller 130 may output a guide message indicating a motion of the mobile terminal 100 in the form of voice or characters such as "please, rotate a key to open the door". Accordingly, the controller 130 may control the motion measure unit 110 to measure the motion of the mobile terminal 100 by the user to compare the measured motion with a motion pattern stored in the motion pattern storage 120.
In addition, the controller 130 may control the image execute unit 160 to simultaneously perform determination of a touch pattern and the displaying of the images of the door and the key. For example, the controller 130 may allow the door and the key to be displayed on the screen of the mobile terminal 100 via the image execute unit 160 as illustrated in FIG. 7, and may control the touch pattern comparator 150 to compare a motion pattern of the key touched by the user and dragged up to the door image with the stored touch pattern.
Therefore, the motion of the mobile terminal is reflected to the images of the door and the key displayed on the mobile terminal to allow the user to have feeling as if the user actually opened the door using the key, and use the mobile terminal intimately and conveniently.
In addition, the user is primarily authenticated based on a touch pattern, and the user is secondarily authenticated based on the motion of the mobile terminal, so that security of personal information stored in the mobile terminal may be reinforced even more.
Though not shown, the mobile terminal 100 may further include a touchscreen unit (called also as a touch detect display, a touch sensitive display, a touch screen or a display), and the touchscreen provides an input/output interface between the mobile terminal 100 and the user. That is, the touchscreen transfers the user's touch input to the mobile terminal 100. In addition, the touchscreen shows an output of the mobile terminal 100 to the user. That is, the touchscreen shows a visual output to the user. Such a visual output is represented in the form of text, graphic, video, and a combination thereof.
The method described above in relation with figures under of the present invention may be provided as one or more instructions in one or more software modules, or computer programs stored in a memory (nor shown) in an electronic device including a mobile terminal.

Here, since the functions and operations of the motion measure unit 810, the motion pattern storage 820, and the controller 830 are the same as those of the motion measure unit 110, the motion pattern storage 120, and the controller 130 of FIG. 1, detailed descriptions thereof are omitted.
As stated above, the touch detect display (not shown) may be included in the mobile terminal. The touch detect display may also be called as the touch sensitive display or the touch screen or a display.
The password storage 840 may store a password set by the user. When the screen lock of the mobile terminal 800 is executed, the user may press an input key installed in the mobile terminal 800 or touches an input key displayed on the touchscreen to input a password. The password comparator 850 compares a password input by the user with a password stored in the password storage 840.
At this point, when the password input by the user coincides with the password stored in the password storage 840, the controller 830 may output a message indicating the motion of the mobile terminal 800, and afterward, the controller 830 may execute secondary user authentication based on the motion of the mobile terminal 800 as described above.
The method described above in relation with Fig. 8 under of the present invention may be provided as one or more instructions in one or more software modules, or computer programs stored in a memory (nor shown) in an electronic device including a mobile terminal.
FIG. 9 illustrates a screen unlock method of a mobile terminal according to an exemplary embodiment of the present disclosure.
Referring to FIGS. 1 and 9, the motion pattern storage 120 may store a set motion pattern for the mobile terminal 100 (910). In addition, the touch pattern storage 140 may store a touch pattern set by the user (920). Here, though the storing of the touch pattern is performed after the motion pattern, this is only an example of a progress sequence and not limited thereto.
The image execute unit 160 may display images of a door and a key on the touchscreen of the mobile terminal 100. When the user touches the image displayed on the touchscreen, the controller 130 may control the motion measure unit 110 to measure the motion of the mobile terminal 100 (930). For example, as illustrated in FIG. 4, the image execute unit 160 may display the door image 410, the key image 420, the handle image 430, and the key hole image 440 on the touchscreen. In this example, when the user drags the key image 420 to insert the key 420 into the key hole 440 via the touchscreen, the controller 130 may receive a response signal corresponding to the drag of the key 420 from the touchscreen, and accordingly, control the motion measure unit 110 to measure the motion of the terminal 100. At this point, when the user inserts the key 420 into the key hole 440 via the touchscreen, the controller 130 may display an image where the key 420 is inserted into the key hole 440. When a primary motion pattern like rotating the key counterclockwise after the key 420 is inserted is measured, the controller 130 may execute the screen unlock.
Alternatively, to reinforce user authentication for the unlock of the mobile terminal 100, a motion pattern may be performed in combination. For example, the controller 130 may determine whether a primary motion pattern of rotating the key counterclockwise has been measured via the motion measure unit 110 after the key 420 has been inserted into the key hole 440 in FIG. 4. In the example where the primary motion pattern has been measured, the controller 130 may determine whether a secondary motion pattern of rotating the handle 430 has been measured. In this example, the primary motion pattern and the secondary motion pattern may be discriminated via a sound effect such as "click" or a message such as "primary authentication has succeeded"
Alternatively, a screen unlock method of the mobile terminal according to the present disclosure may reinforce user authentication by combining a touch pattern with a motion pattern. For example, the touch pattern storage 140 may set and store a touch pattern of dragging the displayed key image 420 up to the key hole 440 as illustrated in FIG. 7, and the touch pattern comparator 150 may be realized to compare a motion pattern of the key image with a stored touch pattern (940). Here, though the displaying of the door image and the key image and the comparing of the touch pattern have been described via one image, the operations may be executed as separate processes as described in FIG. 6. In addition, the screen executed by the image execute unit 160 is not limited to FIG. 4 but various modifications may be possible, of course.
When it is determined by the touch pattern comparator 150 that the motion pattern of the key image coincides with the stored touch pattern (950), the controller 130 may output a guide message indicating the motion of the mobile terminal 100 (960).
When the user moves the mobile terminal 100 according to the guide message, the motion measure unit 110 measures a motion including at least one of a motion direction with respect to the motion of the mobile terminal, a velocity, an acceleration, an angular velocity, an angular acceleration, an amount of change in a slope, and an amount of change in a movement distance with respect to a relevant motion direction (970). At this point, the motion measure unit 110 may measure a motion until the motion is fixed for a set time or more again after the motion starts from a state where the motion is fixed for the set time or more, as one motion pattern. Alternatively, the motion measure unit 110 may determine the start and end of a motion using a specific input key or a touch of a specific point, or determine the start and end of a motion using a pattern of a motion set in advance. Besides these methods, for a method for determining the start and end, for recognizing a pattern of a motion, various modified methods may be applied.
When the motion of the mobile terminal 100 by the user coincides with a motion pattern stored in the motion pattern storage 120 (980), the controller 130 may execute an operation of opening the door with respect to an image displayed by the image execute unit 160 and output a corresponding sound effect or message, thereby executing the screen unlock (990).
Though the controller 130 performs a procedure for comparing a touch pattern with a touch pattern stored in advance, and then measures the motion of the terminal to compare the measured motion with a motion pattern stored in advance in FIG. 9, the controller 130 may measure the motion of the terminal to compare the measured motion with the motion pattern stored in advance, and then compare the touch pattern with the touch pattern stored in advance.
The method described above in relation with FIG. 9 under of the present invention may be provided as one or more instructions in one or more software modules, or computer programs stored in a memory (not shown) in an electronic device including a mobile terminal.
FIG. 10 illustrates a screen unlock method of a mobile terminal according to another exemplary embodiment of the present disclosure.
Referring to FIGS. 8 and 10, a motion pattern storage 820 may store a motion pattern set for the mobile terminal 800 (1010). In addition, the password storage 840 may store a password set by the user (1020). Here, though the drawing illustrates that the storing of the password is performed after the motion pattern, this is only an example of a progress sequence and not limited thereto.
An image execute unit 860 may display an image of a sliding door or display an image of an input keypad of numbers and letters for inputting a password, and an image of a sliding door on the screen of the mobile terminal 800 (1030). At this point, the image of the door that can be displayed on the screen of the mobile terminal 800 is not limited to the image of the sliding door, of course.
When the user inputs a password via an input key installed in the mobile terminal 800 or touches the input keypad image to input a password, a password comparator 850 may compare the input password with a password stored in a password storage 840 (1040).
When the input password coincides with the stored password (1050), the controller 830 may output a guide message indicating the motion of the mobile terminal 800 (1060). Here, though the drawing illustrates that the image of the sliding door is displayed and then a guide message indicating the motion is output according to the input of the user's password, the mobile terminal may receive the password from the user, and when the input password coincides with the stored password, may output the image of the sliding door and the guide message.
When the user moves the mobile terminal 800 according to the guide message, the motion measure unit 810 measures a motion including at least one of a motion direction with respect to the motion of the mobile terminal 800, a velocity, an acceleration, an angular velocity, an angular acceleration, an amount of change in a slope, and an amount of change in a movement distance with respect to a relevant motion direction (1070).
When the motion of the mobile terminal 800 by the user coincides with a motion pattern stored in the motion pattern storage 820 (1080), the controller 830 may execute an operation of opening the sliding door with respect to an image displayed by the image execute unit 860 and output a corresponding sound effect or message, thereby executing the screen unlock (1090).
The method described above in relation with FIG. 10 under of the present invention may be provided as one or more instructions in one or more software modules, or computer programs stored in a memory (nor shown) in an electronic device including a mobile terminal.
FIG. 11 and FIG. 12 together illustrate an example of a touch screen image according to degree of a motion of a mobile terminal used for an exemplary embodiment of the present disclosure. Here, the mobile terminal is one example of an electronic device.
FIG. 11 illustrates a touch screen image and FIG. 12 illustrates a degree of turnover of a screen page in a touch screen image according to degree of a motion of a mobile terminal.
In locked state, a touch screen image representing the locked state is displayed. And the mobile terminal stores a touch gesture for unlocking the locked screen image which is predefined. The touch gesture may a single touch or a single gesture which is to be maintained for a predetermined period.
Unlock of the screen of mobile terminal may be performed when a motion of the mobile terminal corresponding to a predetermined motion is detected while, for example, the single touch is maintained. The predetermined motion may be a motion which is performed in up, down, right or, left direction or a combination of these directions performed by the user's hand. The mobile terminal may be rotated using an elbow of the user as an axis. The gyro sensor is used to detect the rotation of the mobile terminal in the mobile terminal.
The user holds up the mobile terminal using an elbow while the touch in the touch screen is maintained over the predetermined time to unlock the screen of the mobile terminal. That is, unlock of the screen of the mobile terminal may be performed when the mobile terminal is moved up in a rotation-like motion while the touch in the touch screen is maintained.
Also, the user holds up the mobile terminal using an elbow while the touch in the touch screen is maintained over the predetermined time and release the touch to unlock the screen of the mobile terminal. That is, unlock of the screen of the mobile terminal may be performed when the mobile terminal is moved up in a rotation like motion while the touch in the touch screen is maintained and then the touch is released.
The embodiment according to FIG. 11 and FIG. 12 of the present invention may be described in another way hereunder.
A turnover of a page of the touch screen image is illustrated according to degree of a motion of a mobile terminal 100 measured by the motion measurement measure unit 110 is illustrated. Unlock of the screen of the mobile terminal may be performed by a degree of motion of the mobile terminal. Also, the degree of turnover of a page of the touch screen image may be in accordance with the motion of the mobile terminal. For example, if degree of the motion of the mobile terminal is 1/4 of the required motion, then 1/4 of the screen page may be turned over. That means that 3/4 of the locked screen page 1110 may be displayed and 1/4 of the main page (or a page representing a prior performance before the page is locked) 1120 may be displayed underneath the locked screen as illustrated in FIG. 11. In this way, as illustrated in FIG. 12, if degree of the motion of the mobile terminal is 1/2 of the required motion, then 1/2 of the screen page may be turned over. That means that 1/2 of the locked screen page 1210 may be displayed and 1/2 of the main page (or a page representing a prior performance before the page is locked) 1220 may be displayed underneath the locked screen. But, it is also possible to set a condition that locked screen page 1110, 1210 may be fully disappeared and the main page (or a page representing a prior performance before the page is locked) 1120, 1220 may be fully displayed only when the motion of the mobile terminal is fully performed according to the predetermined way.
Also, a touch by, for example, a finger (F) in a predetermined way on a touch detect display may be used as another prior requirement to unlock the screen of the mobile terminal with a degree of motion of a mobile terminal. The first touch may use examples described in the specification with reference to other figures. For example, the first touch may be a first gesture including a touch and a drag of the touch from the touch point to the predetermined location illustrated in FIG. 4, FIG 5, FIG 6 and FIG. 7. Also, the first touch may include multi touches.
Also, there may be requirements for the time maintained before the motion of the mobile terminal. For example, the motion of the mobile terminal may be required within a predetermined time, for example, two seconds or three seconds. If there is no the motion of the mobile terminal, a request to need input of the first touch again may be displayed on the touch detect display. That is, an image is displayed on a touch detect display while an electronic device having the touch detect display is in the user interface lock state. The image may be images illustrated in Fig.4 or Fig. 5. Then, if an image contact on the touch detect display according to a predetermined pattern such as moving the image to the predetermined position or a predetermined touch pattern as illustrated in FIG. 6 is detected, the controller (microprocessor) 830 controls to display a message requesting a motion of the electronic device or output a voice requesting the motion of the electronic device.
Also, a release of the touch (the image contact) may be further required to unlock of the screen of the mobile terminal after the motion of the mobile terminal or at substantially same time with the motion of the mobile terminal.
Regarding the motion of the mobile terminal, a first motion pattern of the mobile terminal is detected, a screen unlock of the mobile terminal is executed if the first motion pattern corresponds to the second motion pattern stored in the mobile terminal and also the image contact is released. Here, the release of the image contact may be performed after detecting the first motion pattern corresponding to the second motion pattern stored in the mobile terminal or may be performed at the substantially same time with detecting the first motion pattern corresponding to the second motion pattern stored in the mobile terminal. Also, when the first motion pattern corresponds to the second motion pattern, the mobile terminal may output a sound effect corresponding to the user interface unlock state and when the first motion pattern of the mobile terminal does not correspond to the predetermined motion pattern, the mobile terminal may output a sound effect corresponding to the user interface lock state.
